Title: Focused beam feeding device
Inventor: DEGUCHI HIROYUKI
IPC: H01Q3/20
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To suppress a cross polarization component sufficiently by sharing a frequency by using a frequency selection film, forming the frequency selection film into a flat surface that is easy to be manufactured and satisfying a cross polarization elimination condition in a wave motion by a secondary curved surface mirror that consists of two pieces of other metal. SOLUTION: A main reflector 1 to an elevation drive shaft 14 and a focusing reflector 21 for a transmitted wave band are the same as the conventional ones, and only a curved surface frequency selection film is changed to a flat surface frequency selection film 20. The film 20 does not generate a dominant cross polarization due to asymmetry of a mirror surface. From the viewpoint of a cross polarization characteristic, the film 20 can be considered to be equivalently replaced with an asymmetrical mirror finished surface such as a secondary curved surface mirror and it can meet a cross polarization elimination condition in a wave motion. With this, it is possible to share a frequency by using the film 20, to have a precision that is better than due to a geometrically optical cross polarization elimination condition and to obtain very low cross polarization characteristics.

Title: Reloadable optical disk device
Inventor: KATO TOMONORI
IPC: G11B7/004
Filed: 1989-08-20
Abstract: PURPOSE:To perform data recording at high speed by executing a retrying operation when the intensity levels of an off-track signal and an off-focusing signal exceed a prescribed threshold value level when erasure and write with one beam are performed. CONSTITUTION:Servo control in a tracking direction and a focusing direction are applied on an optical pickup 3 conforming to the rotation of an optical disk 1. Also, the erasure and the write are performed sequentially with one beam head. The data recording is performed by executing the retrying operation when the level of the off-focusing signal exceeds the prescribed threshold value level in the erasure and the write with one beam. Therefore, conventional verification can be eliminated, which shortens data recording time. Thereby, the data recording can be performed at high speed.

IPC: B41J2/485
Filed: 1985-09-30
Abstract: PURPOSE:To prevent mal-printing and excessive error detection by stopping the action of conversion data to serial data when a delay occurs in receiving the data from a memory bus. CONSTITUTION:At the time when fetching a word from the memory bus, if a bus-right is not acknowledged for a request-to-use-bus, a delay for a portion of N periods of bus-operating clock occurs, and it is probable that the next word to a data latch 2 is not fetched when a counter carry is outputted. When such a state is detected, i.e. a DMAC 1 operates when the counter carry is generated, the conditions are not satisfied for an AND gate 5, an its output is not generated, therefore, a counter 3 and a shift register 4 do not operate. Thereafter, when the next word is fetched in the data latch 2 by a bus-use- acknowledgment signal, the condition is satisfied for the gate 5 and the output is generated. Consequently, the serial shift operation starts. In such a way, a system failure is prevented form occurring, and the availability factor is improved.
